Through BBR, DTT and independently developed Asphalt Thermal Cracking Test, several asphalt low temperature performance indexes(SHRP critical cracking temperature, Asphalt Thermal Cracking temperature, SHRP creep stiffness, m value, conventional ductility) were evaluated. The TSRST test was used as low temperature evaluating standard indicator. The theory of grey correlation is adopted to reach that TSRST fracture temperature has the highest correlation degree with Asphalt Thermal Cracking temperature. The SHRP critical cracking temperature has the second place of correlation degree with TSRST. Low temperature ductility has the lower correlation. Therefore it is more reasonable to adopt thermal cracking temperature than other general evaluations.
